Delx Commerce — Seeded Canary Sequence

x402

Delx Commerce — Seeded Canary Sequence is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Deterministically assigns a list of subjects to ordered stages using a seed, returning a reproducible staged grouping with cryptographic evidence of non-retention.

How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

Output

Returns a JSON object containing a 'stages' array where each element is a list of subjects assigned to that stage, an 'unassigned' array for any subjects not fitting a stage, the operation name, schema version, a 'pass' status, and a cryptographic evidence block including the SHA-256 hash of the input, confirmation that no data was retained, and a count of zero external calls made.

Example use cases

Staged canary deployment planning

“I need to roll out a new feature to our 8 backend services in three canary stages of sizes 2, 3, and 3. Use seed 'deploy-2024-q2' to assign services ['api-gateway','auth-service','billing','notifier','scheduler','worker-a','worker-b','cache'] to stages reproducibly.”

Seeded A/B experiment group assignment

“Assign these 6 experiment participants ['alice','bob','carol','dave','eve','frank'] to two groups of 3 using the seed 'exp-pilot-01' so I can reproduce the same grouping later for analysis.”

Reproducible host rotation for load testing

“I want to deterministically assign 10 test hosts to a canary sequence with stage sizes [3, 4, 3] using the seed 'loadtest-sep' — the host list is ['h1','h2','h3','h4','h5','h6','h7','h8','h9','h10'].”

When to prefer

Choose this endpoint when you need a deterministic, reproducible, verifiable assignment of subjects to ordered stages — especially for canary deployments, staged feature rollouts, or reproducible experiment group partitioning — where cryptographic evidence of non-data-retention matters. Prefer it over local random shuffles when you want pay-per-result accountability and a verifiable audit trail (input hash, zero external calls) without storing any input data server-side.

Side effects

Invalid or missing seed causes malformed request error
stage_sizes array sum exceeds subjects count, leading to partial or empty stages
subjects array exceeds 256-item limit returns validation error
Payment failure via x402 protocol blocks execution before computation
Malformed input types (non-string subjects or non-integer stage sizes) return schema validation errors
